The old classic Z/28 was limited to only 302cid but still put out 500+hp to the crank... so it does have power to hoot. But as stated, today's technology easily surpasses it... suspension, steering, braking, tires, chassis, trans, rear, and greater durability/reliability. The new Z/28 will likely endure longer as well, on & off the track. It would be neat to see a past & present head-to-head! Road & Track... hint, hint. The classic race car looks badass still to this day and worth easily over 100K. Here's the Penske version...

Everything I have ever read said they were 450hp. There is a fully restored one that's over 500hp

If that was rated at the flywheel an LS3 has it beat by a long shot. In a gross rating the LS3 is high 400's almost 500. an LS7 has got to be in the 600hp range.

The 2014 would beat it on pit stops alone the diference in fuel mileage has got to be ridiculous.

I've had 400+ HP carburated SBC's before they can't compete with the LS3 in my 2013. Hell the delivery is insane too. The chassis on my 1LE surpasses anything I've ever built includong a C3 Vette. To get the kind of power out of an SBC that an LS7 or even an LS3 you would have one of the rowdiest beasts you ever saw.

I found a dyno of a 70 boss mustang and it was 455 to the tire. Pretty decent. Also I found an in car 70 boss race car at laguna seca and I was trying to sync it with a video of new boss mustang laguna seca and that seemed pretty similar. The z would walk that car for sure.

A little Googling provided a point of reference. Mark Donahue's fastest lap in winning the 1968 Trans Am race at Mid Ohio was 1:43.7. I have a LOT of experience at Mid Ohio and I can guarantee that the 2014 Z/28 will lap faster than that right out of the box.

What's the avg or best lap time of a modern street car at that track now?

So I'm continuing to answer my own question. The video of laguna seca on old bass I timed at 1.46 and the laguna seca new boss was 1.40. Got to say the in camera of the old car looks like a blast. Check these outhttp://youtu.be/ybCNLNSz5uI
